` l 4 `6 Claims. `This invention relates to means for supporting andlocking theheddle bars of a heddle frame. I

Y One of the principal objects of my present invention is to provideaheddle bar supporting and` Y 5 locking Adevice which is characterized bysimplicity, economy of manufacture and efiiciency in operation when inuse.

Another object of my invention is to provide a heddle bar supporting andlocking means in which a leaf spring is utilized to bear directly uponthe heddle bar and lock it in position in the support, and to also locka center brace in position, supplementary means in the form of a locknut also being provided to positively hold the spring in bindingposition against the heddle bar.

Another object of the vinvention is to provide a construction in whichthe support may be screwed into a wooden heddle framerail by means ofthe usual wood threads, and a locking nut may be mounted on the supporton machine screw threads superimposed on the wood threads.

These and other objects will-more particularly appear as the descriptionproceeds.

In the drawing in which I have illustrated one of the embodimentsthatthe invention may take;

Fig. 1 represents a fragmentary elevational view of a portion of aheddle frame showing the invention applied thereto, the rend portions ofseveral heddles being illustrated in position.

Fig. 2 represents a sectional view on line 2--2 of Fig. 1 looking in thedirection indicated by the arrows.

Fig. 3 represents a similar view on the line 3-3 of Fig. 1.

Fig. 4 represents a view in perspective of the spring.

The same supporting. and locking means may be used in conjunction withthe upper and lower rails of a heddle frame, and I therefore haveillustrated the invention only in connection with the upper rail. Therail is indicated at 5, the heddle bar is indicated at 6, and the upperendsof several heddles are indicated at 'I. The support may be in theform of a pin 8 suitably secured to the rail 5. To this end I mayprovide the upper end of the pin, the lower end of which is flattened asat 9, with wood screw threads IB so that the pin may be screwed intotherail. A reinforcing plate I I may be fastened to the under face of therail, and through al1 openingin this plate the pin projects. Theflattened portion of the pin is provided with a recess for receiving aheddle bar 6, `and this recess at its lower end has a shoulder Iwhich-may be beveled upwardly and outwardly as indicated so as to tendto cam or wedge the (Cl. 139-92) l p heddle bar 6 against thesupport'wherr the bar is in lockedV position. I I

The' locking means for the bar may bein the form of a leaf springI2,"'anchored.at one end to thezplate III by one of lthe screws I3which'sev 5` cure said plate in position, at its other end being forkedas at I4 and provided with a downwardly projecting prong or tongue I5.The forked end of the spring straddles the pin 8, and the spring is thusprevented from turning sidewise, while free to flex up and down,therefore fouling with an adjacent frame is prevented. The prong l5extends downwardly in sufliciently spaced relation to the flattenedportion 9 of the pin to allow for the insertion of the end of a centerbrace I6 between the flattened portion of the pin and the prong. Thebrace may have its upper end hookshaped, so that it may be snapped intoposition on the heddle bar between the support and the prong. The end ofthe prong is recessed at Il 20 so as to engage the upper edge of theheddle bar I5v and force the latter downwardly against the inclinedshoulder I1.

The spring may itself be sufficiently strong to lock the heddle bar inposition on the support.25 and to maintain the center brace in position,but in order to provide a more positive locking means I may utilize alocking nut I8 which is turned onto the pin 8 on machine threads I9which are superimposed on the wood threads. The ma- 30 chine threads'Vmay extend the full length of the I pin except for the flattened portionof the latter, While the Wood threads need only extend a suincientdistance to allow the pin to be screwed to the desired extent into therail and to allow for any adjustments of the pin that may be desired.The locking nut is positioned above the free end of the spring and maybe turned down into the position indicated at Figs. 2 and 3 so as toforce the spring into binding engagement with the heddle bar and thushold the latter rigidly in position in the support; This movement of thelocking nut will likewise bring the nut into binding engagement with thespring so that the latter acts as a means to prevent accidentalunscrewing of the nut. I

When it is desired to remove theheddle bar from its support the nut isunscrewed and the end of the spring lifted to clear the bar whereuponthe latter may be moved outwardly from the recess.

The foregoing detailed description has been given for purposes ofclearness of understanding of the invention, and of the particular formthereof chosen for illustrative purposes, but no undue 55 limitationsshould be deduced therefrom, as the appended claims should be construedas broadly as permissible in view of the prior art.

I claim:

l. The combination with a heddle frame, of a pin mounted on a railthereof and having a shoulder adapted to receive a heddle bar, a springmounted on said rail and having its free end forked and straddl'ilng thepi'n and provided with a prong adapted to engage the heddle' b'ar, and alocking nut mounted on the pin and adapted to be turned into bindingengagement with the spring. v A

2. The combination with a heddle frame, of a pin mounted on a railthereof and having means for receiving a heddle bar, and a2spring'liaiving a portion atlone end adapted to bear against the heddlebar and also having? a portion str'addling the pin.

3. The combination with a heddle frame, of a pin-mounted ori-a railthereof and provided with a shoulder adapted to receive a heddle'bar, aspring mounted Von the rail and having its free end providedv with a=prong adapted toengagel the heddle bar, said prong: beingl arranged i'nsuciently spaced relation to the pin to allow of the reception of acenter brace between the spring and pin, and a locking nut mounted onthe pin and adapted to be brought into binding engagement with thespring.

4. The combination with a heddle bar support having means for receivinga heddle bar, of a spring having a portion adapted to bear against the'heddle bar', said portion extending in spaced relationship with respectto the support to permit the reception of a center brace between thespring and support.

5.- A heddlebar support including a pin having a shoulder adapted toreceive a heddle bar, a spring adapted to engage the heddle bai`directly for locking it in position on the support, and means movablealong said pin for holding the spring and bar in positive lockedposition.

6. A heddle bar support including a pin having a shoulder adapted toreceive a heddle bar, a springl adapted to engage the heddle bar'directly for locking it in' position on the support, and a nut threadedon said pin for holdingthe spring and-- bar in positive` lockedposition.
